Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61616, here are decompositions:
- 3 + 61613 = 61616
- 7 + 61609 = 61616
- 13 + 61603 = 61616
- 73 + 61543 = 61616
- 97 + 61519 = 61616
- 109 + 61507 = 61616
- 199 + 61417 = 61616
- 277 + 61339 = 61616
Showing the first eight; more decompositions exist.
